GUN-SIGHT.

Specification of Letters Patent.

Patented July 20, 1915.

Application filed April 17, 1914. Serial No. 832,545.

To all whom it may concern:

Be it known that I, WILBUR L. WEBB, c1t1- zen of the United States, residing at Bridgewater Corners, in the county of WVmdsor and State of Vermont, have invented certain new and useful Improvements in Gun- Sights, of which the following is a specification.

This invention relates to sights for firearms and more particularly to an improved rear sight especially adapted for use upon pistols or rifles or other small arms.

The invention has as its primary ob ect to provide a sight which may be read1ly shifted, after being applied to ad ust the firearm for point blank range.

A further object of the invention is to provide an adjustable sight so constructed that a minute degree of accuracy may be had in the adjustment thereof.

The invention has as a further 0b]6Cl7 to provide a sight including an elevating shde which is mounted for movement within a slot formed in the arm of the sight to thus raise or lower the head of the sight in which the sight opening is formed, said slot also extending through the head whereby to form shoulders arranged to contact with the slide to thus prevent transverse movement of the sight. And a still further ob ect of the invention is to provide a sight employing an elevating slide carrying an adjusting pin detachably connected with the sl de and which may be filed down or otherwise cut away so that the gun to which the sight is attached may be gradually adjusted to point blank range.

lVith these and other objects in view my invention will be more fully described illustrated in the accompanying drawings and then specifically pointed out in the claims which are attached to and form a part of this application.

In the accompanying drawings: Figure 1 is a side elevation showing my improved sight applied to a pistol, the pistol being partly broken away and conventionally shown. Fig. 2 is a side elevation showing my improved sight applied to a rifle, the rifle being partly broken away and conventionally shown. Fig. 3 is a detail perspective view of the sight showing the elevating slide detached, and Fig. 4: is a front elevation showing the slot formed in the head of the sight, which slot provides retaining shoulders arranged to engage the elevating slide, the elevating slide being shown detached but in proper relative position, this view also showing a conventional form of front sight alined within the sight opening.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

My improved sight is preferably formed from suitable resilient sheet metal and includes an arm 10 adjacent one end of which is formed a dovetail attaching slide 11, such slide being received in a similarly shaped transversely extending slot formed in the gun barrel.

As shown in Figs. 1 and 2 of the drawing, the sight is attached to the gun barrel adjacent the breech thereof so that the vertically disposed head 11 of the sight which is formed by bending the arm 10 upwardly adjacent its free extremity, may be disposed in spaced relation to the adjacent end of the barrel.

The head 11 is slightly enlarged laterally and is preferably rectangular in shape as shown, being arranged transversely of the arm 10 and merging therewith at one corner. Medially formed in the head 11 is a substantially rectangular sight opening 12, the side edges of such opening being arranged parallel with the adjacent sides of the head. By this arrangement it will be observed that a substantially diamond shaped sight opening is provided, and it is intended that when using my improved sight the front sight of the gun shall be brought into alinement medially within the sight opening 19. This is best shown in Fig. 4 of the drawings, the front sight 13 in this figure being conventionally illustrated. It will thus be noted that as the front sight is centered within the sight opening 12, the field within the sight opening will grow larger and that any movement away from alinement will cause the field within the sight opening to grow smaller. This has been found to be a very advantageous arrangement and is an especial feature of advantage in my invention in that the sight opening as thus arranged is not only especially adapted for accurate shooting but is also particularly adapted for quick shooting, since the field of the sight is sufliciently large to permit the sight 13 to be readily brought within such field and at the same time the edges of the sight opening 12 are so disposed that with very little practice the sight 13 may be centered within said opening by the relative disposition of the side edges thereof.

Medially formed in the arm 10 adjacent the head 11 is a longitudinally disposed slot 1 1 which extends through the head 11 to provide a shoulder 15, and forming at the base of the head oppositely disposed vertically extending shoulders 16. Positioned within the slot 14: is an elevating slide 17 which is provided with a straight lower face 18 disposed to contact with the adjacent face of the barrel of the gun to which the sight is attached. The upper face of theslide 17 is cut away to provide a series of stepped teeth or notches 19, inclining from the head 20 of the slide to the free extremity 21 thereof.

The slide 17 is mounted longitudinally within the slot let of the arm 10 and the head 20 of the slide provides by its inner face a shoulder 22 disposed to contact with the adjacent face of the head and is so arranged as to limit the slide 17 in its inward movement within the slot. As will be readily obvious, by adjusting the slot 17, the arm 10 of the sight may be moved vertically with reference to the adjacent face of the barrel of the gun to thus change the range of the sight.

In using my improved sight upon pistols, the head 20 of the slide is preferably dis posed adjacent the head 11 of the sight as shown in Fig. 1 of the drawings. By moving the sight rearwardly, the teeth 19 will be caused to rise over the shoulder 15 of the head, which shoulder is engaged consecutively by said teeth to hold the slide in adjusted position. To return the slide to its normal position, the arm 10 is manually sprung away from the adjacent face of the barrel.

In using the sight upon rifles or other small firearms, the slide 17 is preferably disposed within the slot 14 with the free extremity 21 of the slide arranged adjacent the head 11 of the sight. This is clearly illustrated in Fig. 2 of the drawing. Since the slide 17 normally rests in the position shown when the sight is adjusted at a relatively short range, in which position of the slide, the shoulder 15 of the head 11 will be engaged by the notch of the slide having the least elevation, it will be observed that the greater portion of the slide will be disposed under such conditions exteriorly of the slot 14. In firearms of this character the upper face of the barrel of the gun is generally unobstructed adjacent the breech and thus the free movement of the slide is permitted toward the hammer of the gun. In thus arranging the slide 17 as shown in Fig. 2 of the drawings, it will be observed that the sight may be very easily and quickly elevated by pushing the slide inwardly within the slot 14. Since it is often necessary to shoot quickly with a rifle or similar type of firearm, this arrangement has been found to be very advantageous, for, as just above described, the sight of the gun may be very quickly adjusted. Furthermore, in thus arranging the elevating slide, said slide may be made a relatively greater width than is shown in Fig. 3 of the drawings without in terfering with the vision through the sight opening 12 and thus provide a greater range of adjustment.

The head 20 of the slide is provided with a suitable aperture and detachably positioned within such aperture is apin or stud 23, such stud being vertically disposed and projecting below the lower face 18 of the slide, and being arranged to contact at its free extremity with the adjacent face of the gun barrel. Sights, as applied to guns, are normally arranged to point blank range, and in thus adjusting my improved sight, the slide 17 is disposed at the limit of its inward movement within the slot 14: as shown in Fig. 1 of the drawings. The pin 23 is of such length that when the slide is thus first applied to the gun, said pin will cause the slide 17 to be elevated, when in such position, as to raise the sight slightly above the position where the gun would point blank range. Then, by filing or cutting away the free extremity of the pin 23 so as to lower the slide, the sight may be ad justed to a minute degree. Should the pin become worn, through being moved longitudinally upon the gun barrel, it may be readily removed to be replaced by a new one.

Attention is called to the fact that the slide 17 is guided in its longitudinal movement within the slot 14 by the shoulders 16 of the head, said shoulders being arranged to contact with the side faces of the slide. This is an especial feature of advantage in my invention in that the shoulders 16 not only form guides for the slide but so engage the sight that transverse movement of the head 11 is prevented, since the spring action of the arm 10 is, under normal conditions, sufficient to hold the lower face 18 of the slide and the pin 23 in severe frictional contact with the adjacent face of the gun barrel. In thus providing shoulders 16, the quick adjustment of the slide 17 is facilitated and even though such adjustment be, in haste, roughly done, such shoulders will serve to prevent any lateral springing or disarrangement of the head 11.

It will therefore be seen that I provide a very simple and eflicient structure for the purpose set forth, which is capable of accurate adjustment, and wherein the means provided for such adjustment may be readily removed for replacement.

It will further be seen that I also provide a, and. i

a sight including a sight opening so arranged that the field Within such opening grows larger or increases as the gun to which the sight is attached is brought to an aim and decreases proportionately when the gun is moved away from such aim.

It will still further be apparent that I provide a sight including a resiliently supported head which is formed with a sight opening and provided with guides which not only serve to direct the movement of the elevating slide engaging the head to prevent lateral movement of the head, but also act to prevent lateral movement of the head with relation to the slide.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A sight for guns including a resilient arm adapted to be attached to the gun barrel, a head formed on the arm and having a sight opening, a slide member interposed between the gun barrel and the head for adj usting the elevation of the head, and a pin detachably carried by the slide and engageable against the gun barrel for spacing the one terminal of the slide therefrom, said pin being adapted to be reduced in length for varying the effective height of the slide.

2. A sight for gun barrels including a resilient arm, a head member formed thereon and provided with a sight opening, a slide interposed between the head member and the gun barrel for adjusting the elevation of the head with respect to the gun barrel, and removable means detachably connected to the slide and engageable with the gun barrel for spacing one terminal of the slide therefrom.

3. A sight for guns including an arm, carrying a head formed with a sight opening, said arm having a slot formed therein extending through the head and providing shoulders upon the head, an elevating slide formed with stepped teeth arranged to engage the head, said slide being movable longitudinally within said slot and between said shoulders and a pin detachably connected to said slide, said pin being adapted to be cut away for vertically adjusting the slide.

In testimony whereof I aiiix my signature in presence of two witnesses.
